Let's bring our friends back a few steps, to Episode 2 of Season 1, to the time when anomalies were new. To the time before the anomaly detector, when the team needed to carry around compasses to find them--for, yes, I assure you, it is a compass Connor has around his neck, though the sun entirely blanked out the compass design.
To a time when Connor convinced Abby to go on a camping trip to investigate another possible anomaly site.
To a time when, though Connor liked her from the start, Abby was more interested in learning more about Stephen.
How times do change.
